IMPROVEMENT IN FEATHERING PADDLE-WHEELS.

Specification forming part of Letters Patent No. 189,164, dated April 3, 1 877; application liled October 7, 1876.

To all whom it may concern Be it known that I, HENRY WILLIAMS, of Milwaukee, in the county 'of Milwaukee and State of Wisconsin, have invented a new and Improved Feathering Paddle-Wheel, of which the following is a specification Figure 1 is aside elevation ot' my improved paddle-wheel. Fig. 2 is a vertical section on line a' a: in Eig. l. Fig. 3 isA a detail view ot' Y the feathering-cam.

Similar letters of reference indicate corresponding parts.

My invention relates tothe class of paddlewheels inl which the paddles or doats are feathered in passing into and out of the water; and it consists of a wheel carrying a number of journaled radial arins, having at their outer extremities paddles or doats, which are turned through a quarter of arevolution by T-evers attached to the inner ends of radial arms, which carry a frictionroller at each end. These frictionfrollers move 'in a cam of peculiar construction, which turns the T-le-v vers, and consequently the oats or paddles, at the proper instant.

Referring to the drawing,A isa wheel, provided with thejournal-boxes a a', in which are placed the radial arms b. Paddles or doats B are attached to the outer ends of the arms b, and to the inner ends of the said arms T-levers c are attached parallel to the plane of the paddles. Friction rollers or pins c c which the rollers or pins eengage. The groove d is divided into two parts, d and f, at D. The part d', being the direct continuation of the groove d, receives the foremost pin or roller e, and turns it, and consequently the paddle, through a quarter of a revolution,

iand the partf affords space for the pin c that follows to turn. The part 1L, intervening between the pins e, prevents the paddle from turning while it presents its flat surface to the water. When the pins reach the end of the division they regain their position in the grooved, and retain the paddles edgewise or parallel to the plane of rotation of the wheel through the part of the revolution that the paddles make out of the water.

The feathering part of the cam C is placed so `that the paddles are turned at right angles to the plane of rotation as they ent-er the water, butare turned edgewise or parallel to the plane of rotation before they begin to rise in the water.

Having thus described my invention, I

vclaim as new and desire to secure by Letters Patent- The combination of the stationary cani G,

having the double or divided groove d d j' and intervening solid part h, with the wheel A and radial paddles B, provided with inner cross-arms c, each having pins or rollers c, and moving in the grooves ofthe cam, as and for the-purpose set forth.
